如何在 REST Jersey Web 应用程序中创建、管理、关联会话 [英] How to create, manage, associate a session in REST Jersey Web Application

问题描述

一个 HTML5 UI 连接到后端(REST Jersey 到 Hibernate 和 DB 的业务逻辑).我需要为每个用户登录创建并维护一个会话，直到用户注销.

A HTML5 UI is connected to the backend (REST Jersey to business logic to Hibernate and DB). I need to create and maintain a session for each user login until the user logs out.

能否请您指导我可以使用哪些技术/API.是否也需要在 REST 客户端处理某些事情..

Can you please guide me on what technologies/ APIs can be used. Does something need to be handled at the REST Client end also..

推荐答案

将 JAX-RS 用于 RESTful Web 服务非常简单.这是基础知识.您通常通过 JAX-RS annotations，像这样一个:

Using JAX-RS for RESTful web services is fairly straightforward. Here are the basics. You usually define one or more service classes/interfaces that define your REST operations via JAX-RS annotations, like this one:

@Path("/user")
public class UserService {
    // ...
}

您可以通过这些注释将对象自动注入到您的方法中:

You can have your objects automagically injected in your methods via these annotations:

// Note: you could even inject this as a method parameter
@Context private HttpServletRequest request;

@POST
@Path("/authenticate")
public String authenticate(@FormParam("username") String username, 
        @FormParam("password") String password) {

    // Implementation of your authentication logic
    if (authenticate(username, password)) {
        request.getSession(true);
        // Set the session attributes as you wish
    }
}

HTTP 会话 可以从 HTTP 请求 对象通过 getSession() 和 getSession(boolean) 像往常一样.其他有用的注释有 @RequestParam、@CookieParam 甚至 @MatrixParam 等等.

HTTP Sessions are accessible from the HTTP Request object via getSession() and getSession(boolean) as usual. Other useful annotations are @RequestParam, @CookieParam or even @MatrixParam among many others.
